I've been reading up on installing and SSD drive into the optical drive of a Mac Pro and pairing it with a regular HDD, making a Fusion Drive. However, I have the Mac 3,1 (early 2008), and they don't come ready with SATA cables. More work than I'd like to put in. And not easy from what I gather, because to add a SATA cable from the motherboard to the the optical bay, you'll have to tinker around with parts inside to make it fit properly. Not willing to do that. So then I heard about Seagates SSHD (Solid State Hybrid Drive). Not exactly a Fusion Drive, but apparently some testing sites I've checked, said it's still a speed bump over using a regular HDD. Has anyone use or have any experience with these hybrid drives? Is it worth getting, or stick with a regular HDD. If sticking with a regular HDD. Any suggestions on economical 2TB, 7200rpm drive? While on the topic, does anyone know what the max HDD size can be used on early 2008 Mac Pro Xeon? Tx.
